clarification on GMAT raw to scale conversion scores

Question

Hi, With reference to the below article on the blog:

https://magoosh.com/gmat/2013/how-to-ca ... at-scores/

My raw scores were Q:28, V:30 which translated to Q:46 and V:48 . I used the above chart to convert them to scaled scores. The chart says I scored a 730 but the official GMAT Practice exam software says I scored a 630. Why's there a discrepancy and what should I pay heed to ?

Thanks.

I haven't read that article, but I'll try to help you here.

1. It is very difficult to convert raw scores to scaled scores reliably.

2. Moreover, given that you took a GMATPrep, it is  unnecessary . The GMATPrep itself will report the scaled scores for your test.

3. Although a 28/37 (raw) in quant  may  lead to a 46/51 (scaled) in quant, a 30/41 in verbal will  never  lead to a 48/51 in verbal. 48 in verbal represents an extremely high level of performance, with possibly only 3-4 mistakes.

The GMATPrep tests don't show the latest percentiles, but you will not get a more accurate look at your scaled and total scores outside of those tests. Do not look at the number of questions you got right and instead focus only on the scaled scores reported by the test. The GMATPreps will give you scores out of 51 for both quant and verbal and a total (out of 800). You can always look up the latest associated percentiles  here .

In the link, the data given for raw to scaled conversion is only for quant, so you incorrectly assumed it to be true for verbal, and on top you cant just convert a raw score to scaled score directly like that.
